Gamescope DBus is an open source daemon for Linux that can be used to control the Gamescope compositor over DBus. This interface provides a UI-agnostic way to interact with Gamescope to make it easier to write your own user interface and integrate it with Gamescope.
You can install with:
make build
sudo make installIf you are using ArchLinux, you can install Gamescope DBus from the AUR:
yay -S gamescope-dbus-binThen start the service with:
systemctl --user enable --now gamescope-dbusXML specifications for all interfaces can be found in bindings/dbus-xml.
Individual interface documentation can be found here:
When Gamescope DBus is running as a service, you can interact with it over DBus. There are various DBus libraries available for popular programming languages like Python, Rust, C++, etc.
You can also interface with DBus using the busctl command:
